Gorshkov Summer Student Named Regeneron Science Talent Search Finalist

Timothy Qian, a senior at Montgomery Blair High School, has been named a finalist in the Regeneron Science Talent Search (STS) 2021 competition for the research from his summer research internship at the University of Maryland. He performed the work with the mentorship of JQI Fellow Alexey Gorshkov, who is also a physicist at the National Institute of Standards and Technology and a Fellow of the Joint Center for Quantum Information and Computer Science, and Jacob Bringewatt, a graduate student in physics at UMD. He developed a procedure for using networks of quantum sensors to perform optimal measurements of things like... Continue Reading
Taylor Receives Department of Commerce Gold Medal Award

JQI Fellow Jake Taylor has been recognized by the federal government for his role in expanding U.S. policy and efforts in the fiercely competitive field of quantum information science. Taylor, who is also a physicist at the National Institute of Standards and Technology (NIST), is the recipient of the 2020 Gold Medal Award from the Department of Commerce. Continue Reading
A Frankenstein of Order and Chaos

Normally the word “chaos” evokes a lack of order: a hectic day, a teenager’s bedroom, tax season. And the physical understanding of chaos is not far off. It’s something that is extremely difficult to predict, like the weather. Chaos allows a small blip (the flutter of a butterfly wing) to grow into a big consequence (a typhoon halfway across the world), which explains why weather forecasts more than a few days into the future can be unreliable. Individual air molecules, which are constantly bouncing around, are also chaotic—it’s nearly impossible to pin down where any single molecule might be at... Continue Reading
Science in Quarantine: Microscopy Migrates from Lab to Living Room
In the midst of the global coronavirus pandemic, the luckiest among us have simply been relegated to working from home. And many people have had to find creative ways to turn their home into an office, a classroom, or—in the case of experimental physicists—a makeshift lab. In this episode of Relatively Certain, we bring you a story of one such physicist—University of Maryland physics graduate student Francisco Salces. Before the pandemic, he was developing a new way to measure how good a microscope is at taking pictures of cold atoms in his lab. At home, he figured out a way... Continue Reading
Proposal Shows How Noisy Qubits Might Correct Themselves

One of the chief obstacles facing quantum computer designers—correcting the errors that creep into a processor’s calculations—could be overcome with a new approach by physicists from and the California Institute of Technology, who may have found a way to design quantum memory switches that would self-correct. The team’s theory paper, which was published Dec. 8, 2020 in the journal Physical Review Letters, suggests an easier path to creating stable quantum bits, or qubits, which ordinarily are subject to environmental disturbances and errors. Finding methods of correcting these errors is a major issue in quantum computer development, but the research team’s approach to qubit... Continue Reading
Enhanced Frequency Doubling Adds to Photonics Toolkit

The digital age has seen electronics, including computer chips, shrink in size at an amazing rate, with ever tinier chips powering devices like smartphones, laptops and even autonomous drones. In the wake of this progress, another miniature technology has been gaining steam: integrated photonics. Photons, which are the quantum particles of light, have some advantages over electrons, the namesakes of electronics. For some applications, photons offer faster and more accurate information transfer and use less power than electrons. And because on-chip photonics are largely built using the same technology created for the electronics industry, they carry the promise of... Continue Reading
Kollár Receives Air Force Young Investigator Grant

JQI Fellow Alicia Kollár has been awarded a grant by the Air Force’s Young Investigator Research Program (YIP). She is one of 36 early-career researchers around the US to receive the three-year, $450,000 award. Continue Reading
Two JQI Fellows Named 2020 Highly Cited Researchers

Two JQI Fellows are included on the Clarivate Web of Science Group’s 2020 list of Highly Cited Researchers, which recognizes influential scientists for their highly cited papers over the preceding decade. The two researchers are Sankar Das Sarma, the Director of the Condensed Matter Theory Center and the Richard E. Prange Chair and Distinguished University Professor of Physics at the University of Marlyand (UMD), and Christopher Monroe, Distinguished University Professor and the Bice Zorn Professor of Physics at UMD and a Fellow of the Joint Center for Quantum Information and Computer Science.
